For the second year in a row, Selena Gomez has been named the Trick-Or-Treat spokesperson for UNICEF. The 17-year-old starlet, who recently made a trip to Ghana, Africa for the non-profit organization, shared in a statement, “Trick–or–Treat for UNICEF invites children and adults alike to make Halloween count by joining UNICEF to do whatever it takes to help save children’s lives. This October, I would like to encourage everyone to make a difference and support UNICEF’s mission to reduce the number of daily preventable deaths of children, from 25,000 to zero.” To help the campaign, Selena is also donating four VIP tickets to one of her upcoming concerts with backstage meet-and-greet access to the highest bidder through a Charity Buzz auction. source.
